The pulp trays line is able to process pulp efficiently and produce large quantities of pulp trays quickly. The line can be configured flexibly to produce egg trays and other pulp trays in different shapes and sizes according to customer requirements.
Working steps of pulp egg cartons production
- Waste paper treatment: The waste paper is shredded for subsequent processing and use.
- Pulping: The shredded waste paper is mixed with an appropriate amount of water and stirred into pulp form through a paper pulper.
- Filtration: The pulp is passed through a filtration device to remove impurities and fiber residues to obtain a purer pulp.
- Molding: The pulp is pumped into the forming mold of the egg tray forming machine. The mold squeezes out excess water from the pulp by squeezing and adsorption to form the pulp into the desired egg tray shape.
- Drying: The shaped egg tray is sent into the drying room through a conveyor belt or other devices, and the moisture in the egg tray is evaporated by hot air or other drying methods to dry and cure it.
- Packing: The dried egg trays are inspected and sorted, and packed for storage and transportation.
Available pulp trays press molds
The shape and size of pulp trays depend on the molds of the molding machine. As a professional manufacturer and supplier of egg tray equipment, Shuliy factory can design various molding molds for pulp trays according to customer requirements. We understand that different industries and products may have specific packaging needs, which is why we offer customization options for our clients.
Whether you need plain egg trays, egg crates, or specialized trays for fruits, vegetables, or other delicate items, we can tailor the mold design to meet your specific requirements. Our goal is to provide our customers with high-quality and efficient pulp tray solutions that perfectly fit their production needs.
Recommended drying methods for large scale egg cartons making
When choosing the drying method for egg trays, the size of the production line, budget and space requirements need to be considered. At the same time, make sure the drying process can maintain the quality and shape stability of the egg trays. shuliy factory can provide different types of drying equipment to provide the right solution for customers according to their needs and budgets. For the drying methods of pulp egg trays, the following methods are often recommended by our factory to our customers:
- Natural drying: This is a low-cost drying method. Egg trays can be dried naturally in a well-ventilated area, using ambient air circulation and heat from the sun to gradually dry the pulp egg trays. This method is an economical and practical choice for small-scale production lines or factories with limited space.
- Box dryer: This is a common type of industrial drying equipment and is particularly suitable for large-scale production lines. Egg trays can be placed on trays or grids in the dryer to speed up the drying process by circulating hot air and controlling the temperature. The chamber dryer can provide adjustable temperature and time to ensure that the egg trays reach the ideal drying condition in a short time.
- Continuous multi-layer dryer: This drying equipment is suitable for large-scale production lines and can achieve an efficient and continuous drying process. Egg trays can be dried continuously in multiple levels of drying chambers via conveyor belts or drums. The control of hot air and temperature ensures that the egg trays are evenly dried throughout the drying process.
How to make the surface of the egg tray smooth?
- Quality pulp: Using good quality pulp as a raw material is the key to achieving a smooth surface. Choosing pulp with moderate fiber length and even fiber dispersion can help reduce particles and fiber agglomeration in the pulp, resulting in a smoother formed product.
- Proper pulping consistency: Controlling the pulping consistency of the pulp is one of the factors that affect the surface quality of the egg tray. Too high a concentration may lead to an increase in pulp viscosity, making it difficult to distribute it evenly on the molding mold, while too low a concentration may lead to poor pulp flow. Depending on the characteristics of the equipment and the pulp, adjusting the proper beating consistency can result in a smoother surface.
- Proper forming temperature and pressure: Controlling the forming temperature and pressure during pulp tray forming is important to obtain a smooth surface. Proper temperature can make the pulp flow quickly and distribute evenly in the mold, while proper pressure can make the pulp contact with the mold more closely and reduce the texture and bump of the surface.
- Selection and maintenance of forming molds: The design and condition of the forming molds also affect the quality of the egg tray surface. Choose high quality molds and make sure the surface of the mold is smooth and free from damage. Inspect and maintain the molds regularly and repair any worn or damaged parts in time to maintain a smooth surface.
To enhance the production efficiency of egg cartons, Shuliy factory offers a dedicated commercial hot press machine designed to flatten the surface of pulp trays. This hot press machine enables rapid thermal pressing of each individual egg carton, resulting in a smooth surface.
With this equipment, the pulp trays undergo a heat treatment process that ensures their surfaces are perfectly leveled and free from imperfections. This advanced hot press machine provided by Shuliy factory is an effective solution to achieve high-quality and aesthetically pleasing egg cartons efficiently.
